This invention relates to new and useful improvements in blow torches and the primary object of the present invention is to provide a blow torch embodying novel and improved means for conducting a fluid from a tubular body into a burner so that the same may be employed to heat the end of a soldering iron.

Another important object of the present invention is to provide a gas blow torch including means for supporting a soldering iron at an inclined vertical angle so that the end of the iron will be positioned relative to the burner portion of the device for maximum heating and observation thereof.

A further object of the present invention is to provide a blow torch including valve means for regulating the amount of heat applied to the soldering iron.

A still further aim of the present invention is to provide a gas blow torch that is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the present blow torch;

Figure 2 is an end view of Figure 1;

Figure 3 is an enlarged side elevational view of the present invention, and with parts broken away and shown in section; and

Figure 4 is a longitudinal horizontal sectional view taken substantially on the plane of section line 4-4 of Figure 1.

Referring now to the drawing in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It] represents a flat substantially squared base plate, to the center of which is fixedly secured one end of a vertically disposed tubular post I2.

Adjacent one end of the post I2, there is provided a pipe I4 coupled to a hand-operated valve I6 having a reduced extension l8 that engages a flexible tube 20 leading from a source of fluid, preferably natural gas.

Preferably integrally formed at the upper end of post I2 is a burner sleeve 22, disposed at right angles to the axis of post i2 and having air vents 24 provided in opposite sides thereof.

post I2.

1 laim. (o1. lac-23?) The numeral 26 represents a; substantially U-shaped conduit generally, substantially tubu lar'iilformand having one leg 28 elongated and fixedly secured adjacent the upper end of the The inner end 30 of leg 28 is turned upwardly in the center of the post and is spaced slightly from the lower periphery of the burner sleeve closing the upper end of the post. The opposite leg 32 of the conduit 26, is spaced from one end of the burner sleeve and is provided with a spray tip 34.

Rigidly secured to the upper periphery of the burner sleeve 22 near conduit 26, is the lower portion of an upstanding hook member 36 that engages the shank portion 38 of a soldering iron 40. At the opposite end of the burner sleeve there is provided a bearing plate 42 having a notched portion 44 that engages the shank of the soldering iron 40. The bearing plate is of such a size that the shank 38 will be inclined at a vertical angle relative to the axis of the burner sleeve 22 and the tip 46 of the soldering iron will be positioned adjacent the forward end of the burner sleeve.

In practical use of the device, when valve I6 is placed in an on position, fluid will pass through tube 20 into the post l2, rise in the post to engage the lower periphery of the burner sleeve, be deflected into conduit 30 and hence outwardly from tip 34. A match may be held at the tip 34 to ignite the fuel which will cause a flame to be projected through the burner sleeve 22 to engage the tip 46 of the soldering iron.

By such an arrangement, the valve l6 being disposed away from the heated chamber 22, may be easily activated in a safe manner. Further, the tip 46 of the soldering iron may be observed for removal at a selected time. Also, the gas may be ignited with convenience in a safe manner. It should be noted that the sleeve 22, the conduit 26 and pipe I4 are disposed in a vertical plane which preferably extends diagonally with the corners of the base plate I4, to ofier greater rigidity to the structure although the size of the base plate may be relatively small.

In view of the foregoing description taken in conjunction with the accompanying drawing it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A gas blow torch comprising a substantially rectangular base plate, a tubular post fixed to the center of said base plate, a perforated burner sleeve fixed to and closing the upper end of said post, an inlet conduit fixed to said post, said sleeve and said inlet conduit aligning diametri cally opposite corners of said base plate, a substantially U-shaped conduit having an elongated leg fixed to said post adjacent said sleeve, the

inner end of the elongated leg being turned upwardly within the post and spaced'from the burner sleeve, the remaining leg of said U-shaped conduit terminating adjacent the burner sleeve and supporting a spray nozzle, and means carried by the burner sleeve for supporting a soldering iron, said U-shaped conduit aligning the inlet conduit.
